QuestionWill it charge heated camping chairs
Asked 6 months ago by Anonymous.
- Answer Hi RodolfoG， Thanks for asking! The Energizer MAX 20,000mAh 15W USB-C Power Bank can potentially charge heated camping chairs, but it depends on the power requirements of the chair. Here’s what to check: If your heated chair uses USB power (5V/2A or 5V/3A), this power bank should work fine. If the chair requires higher voltage or wattage (e.g., 12V or more), this power bank won’t be compatible. Also, keep in mind that heated chairs can drain the battery faster due to continuous power draw. We recommend checking your chair’s input specs before use. If you’re unsure, feel free to share the model and we’ll help confirm compatibility.

QuestionHi I just bought this energizer portable battery but it takes forever to charge, is that normal? I connected it using the black charger provided with the portable battery, but got it to move just one percent up it takes about an hour
Asked 1 year ago by Pink.
- Answer I did notice that it takes a long time to charge. However, the longer charging time is compensated by the power bank's extended battery life. So to answer you question, I believe its normal for it to take a long time because it's designed to deliver a long-lasting charge.
